PROTECTIVE ENVELOP FOR GLASS RECEPTACLES.

Specification of Letters Patent.

Patented Mar. 12, 1912.

Application filed February 5, 1910. Serial No. 542,326.

To all whom it may concern:

Be it known that I, Or'ro DOMNICK, of Aken a. d. Elbe, Prussia, German Empire, a subject of the King of Prussia, and whose post-office address is Burgtor 2, Aken a. d. Elbe, Prussia, German Empire, have invented a new and useful Protective Envelop for Glass Receptacles, of which the following is a specification.

This invention relates to protective envelops for inclosing glass receptacles and especially such as are intended to contain sulfuric acid or other chemicals. Hitherto the packing of such receptacles has been effected by placing them in baskets, and filling the space between the sides of the basket and the receptacle with straw, but owing however to the unequal distribution of the straw 15 to 20% of the glass receptacles are broken. On the other hand straw envelops for bottles and larger receptacles are already known, wherein the packing is effected by straw mats or straw sleeves, which are held by means of a wire net in position upon the receptacle consequently forming an integral part of the receptacle. In order to avoid the above mentioned defects, a straw or the like envelop intended for packing the glass receptacles, is prepared so as to correspond to the size and shape of the receptacle which is to be inclosed, so that after the glass receptacle has been inserted, it is contained tightly within the envelop whereby the envelop can be used over and over again for protecting receptacles. In order to effectively pro tect the parts most liable to damage, the upper and lower edges of the straw envelop are turned over or doubled to inclose a straw rope or the like.

Reference will now be made to the accompanying drawing which shows a protective envelop in position, partly in section.

The straw envelop b fitted to a glass receptacle a of the type used for containing sulfuric acid, is made to correspond to the shape of the receptacle, so that it may be inserted in the envelop immediately. The envelop is sewn together with string or the like at the top, in the middle, and at the bottom, and for insuring not only long wear for the envelop but also special protection to the parts of the glass receptacle, most liable to damage, the upper and lower edges of the straw envelop are turned over or doubled so as to inclose a straw rope or the like and then sewn. Preferably only the upper edge is provided with a straw rope c, the lower edges (Z being simply brought together and then sewn fast. Finally, it must be remarked, that straw envelops constructed according to the invention may be mamifactured exceedingly simply and cheaply and further that they are easy of transport since one may be inserted within the other, thereby occupying a minimum of space.

lVhat I do claim as my invention, and desire to secure by Letters Patent of the United States, is

1. As an article of manufacture, an envelop for fragile receptacles formed of straw shaped to the receptacle, the lower edges of the straw being doubled on themselves and sewed together to form a fiat closed lower end for the envelop and the upper edges of the straw being doubled on themselves, and a straw rope inserted through and secured in said doubled upper edges of the straw.

2. As an article of manufacture, an envelop for fragile receptacles formed of straw shaped to the receptacle and having a flat bottom portion, the straw forming the envelop being secured by stitching intermediate the upper edge and the flat bottom portion, the upper edge of the straw being doubled outwardly on itself and secured by stitching, and the lower edge of the straw being doubled on itself and secured together by stitching to close the bottom of the envelop.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

OTTO DOMNICK.
